Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the Radeon R7 370 2G should be 182% quicker than the Radeon HD 4850 512MB in general, because of its higher bandwidth. (explain)

Radeon R7 370 2G		179200 MB/sec
Radeon HD 4850 512MB		63552 MB/sec
	Difference: 115648 (182%)

Texel Rate

The Radeon R7 370 2G should be much (more or less 150%) more effective at AF than the Radeon HD 4850 512MB. (explain)

Radeon R7 370 2G		62400 Mtexels/sec
Radeon HD 4850 512MB		25000 Mtexels/sec
	Difference: 37400 (150%)

Pixel Rate

The Radeon R7 370 2G is much (approximately 212%) faster with regards to FSAA than the Radeon HD 4850 512MB, and able to handle higher screen resolutions better. (explain)

Radeon R7 370 2G		31200 Mpixels/sec
Radeon HD 4850 512MB		10000 Mpixels/sec
	Difference: 21200 (212%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of information (measured in MB per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
